REMOVABLE CALK FOR HORSESHOES.

To all whom it may concern Be it known that I, HARRISON R. YOUNG, a citizen of the United States of America, and a resident of Gat-asauqua, county of Lehigh, and State of Pennsylvania, have invented certain new and useful Improvements in Removable Calks for Horseshoes, of which the following is av specification, reference being had .to the accompanying drawing, forming a part thereof.

My invention relates to horse-shoes and the like and one of its objects is to provide a rigidly aflixed, removable calk for shoes of this character, that shall be simple and.

durable in construction and easy .to attach and detach.

Other objects will be set forth hereinafter.

I will describe my invention in the following specification and point out the novel features thereof in appended claims.

Referring to the drawings: Figure 1 is a face or bottom plan view of a shoe constructed for and equipped with removable calks which are constructed and arranged in accordance with my invention. Fig. 2 is a sectional elevation on the line 22 of Fig. 1. Fig. 3 is another sectional elevation on the line 33 of Fig. 1. Fig. 4 is a perspective view on a larger scale, of one of the heel sections of the shoe shown in Fig. 1, the heel calk being spaced from the section of the shoe to disclose in detail the structure of the cooperating parts.

Like characters of reference designate corresponding parts in all the figures.

10 is a horse-shoe formed in the usual manner with nail holes 11. The body of the shoe is preferably provided with a toe projection 7 and heel projections 8-8 which increase the thickness of and thus reinforce the shoe at the points where calks are usually located.

Notches or slots 1212 are provided on opposite edges of the shoe where it is reinforced by the projection 7, and notches or slots 1318 and 1414L are provided in the shoe at the reinforced heel portions. These notches produce spaced parallel shoulders 12, 13, 14 and interposed rectangular sections 1516 and 17 which are thicker and narrower in cross-section than the remainder of the shoe. A toe calk 18 is removably mounted on the section 15 and heel calks 19 and 20 are removably mounted on the sections 16 and 17. The toe calk 18 is longer than the heel calks 19 and 20, but is similar Specification of Letters Patent.

to them in form, and each of the calks comprises a block which may be fiat or sharpcried as desired and is provided with a longi tudinal rectangular mortise 22. As shown in l of the drawings, the mortise is of such a size and its side walls ME- 24 are of sue-h a width that the calk fits onto the rectangular section 17 of the shoe between the shoulders. Bolts or machine screws 25 extend through holes 23 in the walls 24 and through corresponding holes in the shoe sections. 'Thus-i-t appears that the calks are not only mortised to fit onto the rectangular vided with side notches forming parallel 1 shoulders between which the side projections of the calks extend. This arrangement makes the joint between each calk and the shoe a particular rigid one. There are however, no beveled or inclined surfaces such as are found on dovetail joints and are liable to become damaged and to prevent the ready removal of the calk. lVith the arrangement illustrated, the flat top surfaces of the projections are engaged by the flat under surfaces of the calks and consequently the weight of the animal does not tend to displace the calks but is advantageously sustained. Furthermore, there is no stress on the bolts so they are not liable to be sheared off or damaged, but they hold the calks securely in place so that they cannot be displaced while in use, and the shoe, together with the removable calks, can be easily forged.

Two interchangeable sets of calks may be provided for each shoe if desired, one set having flat bearing surfaces and the other being sharpened or beveled to prevent slipping.

The body of the calk may be longer than the rectangular section of the shoe to which it is secured as is the toe calk 18 illustrated. in the drawings, or the calk may be of the same length as the corresponding shoe section as are the heel calks illustrated.

My invention is of course not limited to removable calks for shoes for horses, as distinguished from those adapted for use on mules, oxen, etc, and I have used the term horse-shoe broadly as indicating a shoe of this general character.

What I claim is:

1. A horse-shoe having a projection extending from its face and opposite edge notches in the shoe extending at right angles to the face, through said projection, arranged to form parallel spaced shoulders, separated by a rectangular shoe section of reduced Width and increased thickness, and a calk reniovably secured to said section and having projections fitted into said notches between the shoulders.

2. A horseshoe having reinforcing projections extending from its face and open ended opposite edge notches in the shoe eX- tending at right angles to the face of the shoe and arranged to form spaced shoulders in the reinforced portions, separated by a rectangular shoe section of reduced Width and increased thickness, and toe and heel calks reinovably secured to said sections, each of said calks being niortised to fit onto the corresponding rectangular section, and arranged to fit between said shoulders.

3. A horse-shoe having reinforcing projections extending from its face With plane fiat outer surfaces and open ended opposite edge notches in the shoe extending at right angles to the face through the reinforcing projections and arranged to form parallel spaced shoulders, separated by a rectangular section of reduced Width and increased thickness, and toe and heel calks reniovably secured to said sections and having fiat under surfaces to engage the flat outer surfaces of the reinforcing projections and sustain the Weight of the animal, each of said calks being inortised to fit onto the corresponding rectangular section of the shoe and arranged to fit between said parallel spaced. shoulders.

In testimony Whereof, I have hereunto set my hand, this 29th day of March, 1913, in

the presence of tWo subscribing Witnesses.
